Hi Sebastian,

which version are you using? I looked into 3.0 and 4.0, and there is nothing there about setting packageList to nil in MCFileRepositoryInspector.

Objet : [Pharo-dev] Workaround monticello issue

Hi there,

I�ve just hit an issue that prevented to open packages in monticello

MessageNotUnderstood: receiver of "indexOf:" is nil
UndefinedObject(Object)>>doesNotUnderstand: #indexOf:
MCFileRepositoryInspector>>packageSelection
PluggableListMorph>>getCurrentSelectionIndex
PluggableListMorph>>updateList
PluggableListMorph>>update:
MCFileRepositoryInspector(Object)>>changed: in Block: [ :aDependent | aDependent update: aParameter ]
DependentsArray>>do:
MCFileRepositoryInspector(Object)>>changed:
MCFileRepositoryInspector>>refresh
MCFileRepositoryInspector>>setRepository:workingCopy: in Block: [ ...
BlockClosure>>newProcess in Block: [ ...

This is what I�m using as hacky workaround:


MCFileRepositoryInspector>>packageSelection
^ self packageList isNil
ifTrue:[ 1 ]
ifFalse:[ self packageList indexOf: selectedPackage ]

The problem is that packageList is nil for some reason.

Looks like filetree is involved since
1. I�m using it and 
2. it sets an extension method #refresh that makes packageList := nil
